The Tauber Family Railroad has been a favorite at the Detroit Zoo, serving nearly half a million passengers each year, since it was presented by The Detroit News in 1931.
Today's train consists of two complete trains of six coaches each and one standby. All three locomotives were donated by the Chrysler Corp. in the 1950's. In 1982-83, the locomotives were renovated and new coaches were fabricated through a fund-raising campaign by The Detroit Zoological Society and The Detroit News.
